Process & Technology

According to Wiped-Film-Evaporation ("WFE") is the state-of-the-art, proprietary technology to produce higher process efficiencies by minimising bottom components and maximising reclamation of the useful ingredients from used lube oil. WFE technology can extend the yields of the products up to 95% - 97% of the used oil feed. The high yield in the WFE process is due to the innovative equipment design and design optimizations of the process.

WFE process is acid-free, solvent-free and sludge-free. The bottom residue generated in the process may be sold as finished product, such as asphalt/bitumen modifier.

The modular design not only offers quick and sturdy installation, but it also offers a unique flexibility to increase the plant capacity in future by the addition of modules without additional infrastructure. Entire set up & commissioning of the plant takes only 4 to 6 weeks as complete plant is built and tested for its proper functioning at the factory. This enables a quick start up.

WFE adapts very well to feedstock variability such as used lube oils containing high amount of water, low boilers, additives, transformer oils, turbine oils, hydraulic and synthetic oils.

Complete automation, Programmable Logic Controller ("PLC") control and Supervisory Control and Data Acquisition ("SCADA") based process enables asafe and smooth plant operation with minimum manpower, in an environment-friendly manner.
